Memories about memory cards

18th December 2018

What do you know about memory cards, their history and evolution?

In today’s ‘smart’ world so much of what we do relies on data. As technology has evolved, demand for memory has grown. The need to store and process data is nothing new though, and here we take a brief look back at the history of memory cards…

1725

The first time that data was stored on a card, back then it was a simple punch card which was used to automate a drawloom for weaving fabric/tapestries.

1884

Punch cards were used in the Holleirth Electric Tabulating System (described as being an electro-mechanical excel). Holleirth later started the company which ultimately became the foundation of IBM.

1965

Considered back then to be the first commercial desktop computer (we’d say it was a rather large calculator), the Olivetti Programma 101 used a long magnetic card to store data and instructions.

1991

The first ever SIM card was developed by Giesecke & Devrient. In the early days SIMs stored only 20 numbers and 5 texts.

1997

Siemens and SanDisk unveiled the first ever MMC (MultiMedia card). Unsurprisingly the first mobile to support the removable MMC was the Siemens SL45.

1998

Sony launched the Memory Stick, used in a range of Sony products including digital cameras, PCs, the PlayStation Portable (PSP) and mobile phones. Sony’s version of a microSD, the Memory Stick Micro (M2), followed. Memory Stick adoption outside of Sony was low, with other manufacturers favouring SD cards. By 2010 all Sony products had switched to SD cards.

2000

The new millennium saw the advent of the first Secure Digital (SD) card, a collaboration between compliments of SanDisk, Matsushita (Panasonic) and Toshiba.

Whilst MMC and SD cards were electrically compatible, the latter was half a millimetre thicker, meaning SD cards wouldn’t fit into devices with MMC slots. As a result, MMC and SD cards co-existed for a time, but in the long run only SD cards, along with microSD (2005) and miniSD (2003) cards, survived.

2004

RS-MMC (Reduced Size MMC) were introduced, with Nokia being an early adopter.

Whilst you no longer see removable MMCs, the standard lives on in an embedded format (eMMC), favoured for cheaper mobile phones.

2012

The Universal Flash Storage (UFS) was announced by JEDEC. The aim of this new specification being to bring higher data transfer speed and increased reliability to flash memory storage, while reducing market confusion and removing the need for different adapters for different types of card.

Samsung invented 3D NAND, technology that would revolutionise the data storage industry.

2016

Samsung launched the first UFS cards and UFS/microSD hybrid slots, but despite offering some performance advantages over SD, SD cards remain the memory card of choice for consumers and manufacturers.

2017

The A2 application performance class is released by the SD Association.

2018

The SD Association announced the new SD Express, a new standard which offers enhanced read/write speeds thanks to the implementation of NVMe (Non-Volatile Memory Express) for SD cards. Hopes are that NVMe will come to microSD cards sooner rather than later.
